摘要：
A hypothesis is proposed for a change in the spin state of a two-center two-electron bond of a reacting molecule under the perturbing action of an organic radical. The hypothesis opens up new possibilities for refining the mechanism of radical bonding to olefins and conjugated dienes. A change in the spin state of the ethylene and s-trans-butadiene-1,3 molecules creates prerequisites for one-electron transfer in the reaction system. Single-electron transfer changes the distribution of effective charges on the atoms of the reaction system, ensuring their Coulomb interaction and allowing us to interpret the formation of final products in the context of a fundamental physical interaction (electromagnetic).
